    USB Cable Included.

    Keeping it Simple

    Media WriteBlocker has one output (USB 2.0) port and one status LED. It’s so simple – there is nothing to configure – and is consquently very easy to use. Simply attach the Device Under Capture and connect Media WriteBlocker to the computer. The LED confirms power to the device and simultaneously confirms that the write-blocking technology is active.

    Software Utility

    Usually the Operating System has access to information about a volume attached through USB. Because Media WriteBlocker is acting as a filter, the Operating System only sees Media WriteBlocker. Forensic Software Utility will display information about devices connected to Media WriteBlocker, and allow you to save them as text files for inclusion in case reports.
